I hate just quoting a link and telling you to use the search function but you really could've saved yourself the time.

This is one of the more hairy topics to approach. However, I have a failsafe way to handle it. Basically, each chunk can contain 4 textures (each on a layer), which each can have a specific applied groundeffect ID. The ID is further defined within the .dbc, however, this is not important. The most important thing is simple; Wow tries to visual a groundeffect for a texture that is not existing. On a chunk with 3 layers, but 4 ground effects noted, it is bound to lead to a "false", leading to a crash.
A simple fix is easy; simply use the texture painter, apply some texture, set it to some size but the lowest speed and apply it onto the adt, until every chunk has 4 layers. The crashes stop.
Another possibility is to remove all the groundeffects IDs (MCLY) for every chunk, or even specific chunks, to avoid the problem. Refer to the 010 Editor for that.
The last one is to completely change the groundeffects according to needs. Either by hex, or getting a tool (post it once you have it.)
Refer to this section, basically make sure each Chunk of your ADT has 4 textures, sounds like you're editing Blizz ADT's and this happens almost always, if not -Always- so just check all your Chunks, then open up the texture painter, set opacity and pressure to 0 or closest and paint over the whole ADT until each chunk has 4 textures.
It won't effect your edit's as long as you make sure your brush settings are fine, but as always keep backups and recognise this isn't a permanent fix, and can cause problems later so plan around them and again, backup!
Good luck on fixing your problem and promise to check out that link I put at the top!
